Abstract
A method of fabricating a hologram screen having a large visual range and a hologram imaging apparatus used for the particular method of fabricating the hologram screen are disclosed. A plurality of mirrors () extended toward a plurality of photosensitive members () are arranged at a plurality of end portions (), respectively, of a light diffuser (). At least a reference beam () and object beams () passed through the light diffuser () are radiated on a plurality of the photosensitive members () individually thereby to form a plurality of holograms. These holograms are integrated with each other by being arranged two-dimensionally thereby to fabricate a hologram screen. Among the mirrors (), a reference beam-side mirror () arranged nearer to the light source of the reference beams () is extended from the light diffuser () by a length varied with the position of the photosensitive member () to be exposed.
